Abstract: PURPOSE:To enable operational power, which can be output within the essential restriction of a machine, to be displayed to the maximum limit, by providing a limiting circuit for a rate of change in an output so that a gas turbine holds the rate of change in its inlet temperature to a specified value or less. CONSTITUTION:In the case of a gas turbine having a compressor 1, combustor 2 and a turbine 3 as the principal equipments, an output 7 of a generator 4 generates a deviation from a value, obtained from an output request value 8 through a change rate limiter 10, and a fuel regulating valve 5 is controlled through a valve driving gear 14 by a control signal which is obtained being calculated in an arithmetic unit 12 so that this deviation decreases to 0. Here the gas turbine obtains in a subtractor 17 a deviation of the temperature change rate, obtained by differentiating an output of a turbine inlet temperature detector 9 by a differentiator 16, from a temperature change rate limit preset value 18. And the gas turbine, so that the above deviation decreases to 0, is constituted collating a control signal, obtained being calculated in an arithmetic unit 19, with the control signal from an arithmetic unit 12 in a low value selecting circuit 20 and selecting either of the signals of lower value so as to be output to the valve driving gear 14.

Title: Keyless tool chuck
Inventor: UEN HAATOREI
IPC: B23B31/12
Filed: 1987-03-18
Abstract: PURPOSE: To require no chuck key for use by providing an impact plate extrudable or retractable along a drill portion, operating a drill in contact with a drive flange controlling the rotation of a toothed chuck flange with it, and applying rotation to the chuck flange at a speed different from that of a jaw. CONSTITUTION: A chuck jaw 18 is extruded or retracted by rotating a shaft 28 while the rotation of a chuck flange 20 is reduced or stopped. This is conducted by an impact plate 24 while the shaft 28 is rotated, and the impact plate 24 is extruded along the length portion of the shaft 28. The impact plate 24 is brought into contact with a drive flange 22 by the complete extrusion, and it is coupled with the chuck flange 20 and rotated together. When the impact plate 24 is retracted, the chuck flange 20 and the drive flange 22 are rotated at the same speed as that of the shaft 28 due to the contact between the chuck jaw 18 and the chuck flange 20. When the impact plate 24 is extruded into the drive flange 22, the rotation of the drive flange 22 and the chuck flange 22 is reduced and stopped because the impact plate 24 is not rotated.

Title: Picture data transmission system
Inventor: MURATA NAOMITSU
IPC: H04N1/32
Filed: 1988-03-15
Abstract: PURPOSE:To transmit picture data at high speed by transmitting the picture data by a second minimum unit time longer than a first minimum unit time when the quantity of the picture data not yet transmitted in a storing means becomes below predetermined data quantity. CONSTITUTION:The title system is provided with a removably-mounted picture reader 2 and the storing means 3 to store the picture data by every unit quantity. Then, when the transmission processing of the picture data is performed at speed higher than that of the reading processing of it, and the picture data quantity not yet transmitted in the storing means 3 decreases and becomes below the predetermined data quantity, the second minimum unit time is set, and the transmitting processing of the picture data is performed at low speed. Accordingly, even if manual scanning is performed at low speed, since time until a receiving side transmission equipment is stopped can be selected to be longer, the transmission of the picture data can be performed uninterruptedly. Thus, the picture data read by the manual scanning is transmitted in real time. Thus, the transmission of the picture data can be performed at high speed.
